I was not aware that the source code could be obtained here.
What do you mean by "still"? Which options are broken?
mostly in the beta content portions, but also getting errors in some places in the prologue
Where, exactly? It's hard to fix problems unless I know specifically where they are.
In the part where you reunite with Chiaki after becoming the demifiend, when you convince her it’s really you, the only option that works is killing her. The other option is an error
Okay, I have a hypothesis for why that's happening and I'll try to fix it tomorrow.
